Coastal Flood Warning
Issued: 6:44 AM Dec. 19, 2025 – National Weather Service
...COASTAL FLOOD WARNING REMAINS IN EFFECT FROM 6 AM TO 11 AM EST THIS MORNING... * WHAT...1 1/2 to 2 ft of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. * WHERE...Southwest Suffolk County. * WHEN...From 6 AM to 11 AM EST this morning. * IMPACTS...Widespread minor to moderate flooding of vulnerable areas near the waterfront and shoreline. Expect 1 1/2 to 2 ft of inundation above ground level in low lying, vulnerable areas. This will result in numerous road closures and cause widespread flooding of low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront. Vehicles parked in vulnerable areas near the waterfront will likely become flooded. Flooding will also extend inland from the waterfront along tidal rivers and bays. * SHORELINE IMPACTS...Breaking waves of 8 to 12 ft along the oceanfront during the time of high tide will result in widespread beach flooding and erosion, with scattered areas of dune erosion. Wave splashover is not likely. * ADDITIONAL DETAILS...Heavy rain during the time of high tide may exacerbate flood impacts. This forecast is leaned towards a higher end flood impact scenario, to account for slower trend in cold frontal passage and potential coincidence with heavy rain. PRECAUTIONARY/PREPAREDNESS ACTIONS... Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. && Time of high total tides are approximate to the nearest hour.
